This kit demystifies DNA's and RNA's connection to protein synthesis.

• Demystify the DNA/RNA connection
• Model replication, transcription, and translation
• Time required: one 50 minutes class period

Students construct a model of DNA, replicate it, and use half of the ladder to build messenger RNA (mRNA). Placing mRNA on a model ribosome simulates transcription in the nucleus and the movement of mRNA. Students simulate translation by matching the mRNA and its codons to transfer RNA (tRNA) and its anti-codons.

Amino acids bond to form a protein molecule, and students experience how information stored in DNA is expressed as a finished protein.
